“…Each oyster species has an optimal salinity concentration for growth, with 15-18 ppt (parts per thousand), 20-25 ppt, 20 ppt and 25-35 ppt being the optimal range for C. virginica, C. gigas, O. edulis and S. glomerata respectively (Nell and Holliday, 1988;Wallace, 2001;FAO, 2016a;. Shifts from these optimal ranges can occur following rainfall events, periods of extended drought, tidal changes and from wind-driven flow (Geyer, 1997;Drexler and Ewel, 2001;Schmidt and Luther, 2002;Da Costa et al, 2016).…”

Shifting environmental conditions are known to be important triggers of oyster diseases. The mechanism(s) behind these synergistic effects (interplay between host, environment and pathogen/s) are often not clear, although there is evidence that shifts in environmental conditions can affect oyster immunity and, pathogen growth and virulence. However, the impact of shifting environmental parameters on the oyster microbiome and how this affects oyster health and susceptibility to infectious pathogens remains understudied. In this review, we summarise the major diseases afflicting oysters with a focus on the role of environmental factors that can catalyse or amplify disease outbreaks. We also consider the potential role of the oyster microbiome in buffering or augmenting oyster disease outbreaks and suggest that a deeper understanding of the oyster microbiome, its links to the environment and its effect on oyster health and disease susceptibility, is required to develop new frameworks for the prevention and management of oyster diseases.

“…Further, floods and droughts are also expected that can affect the transitional ecosystems, such as the mangroves. Shifts www.mercator.ufc.br ROSSI, S.; SOARES, M. O. in salinity, organic matter, contaminants, and nutrients induced by extreme floods and droughts have drastic effects on mangroves (PEREIRA et al 2013;COSTA et al 2016;SLOTERDIJK et al 2017).…”

Since the 1980s, the effects of the El Niño phenomenon have been taken note of seriously from an ecosystem and economic point of view. After the fishing debacle in the 1980s, in countries, such as Peru and Chile, and the phenomena of coral bleaching detected worldwide due to the intense changes in the oceanographic conditions, the effects of this phenomenon have been studied more systematically (since El Niño 1997-98). Without having the absolute certainty of whether climate change is increasing the frequency or intensity of its impacts, what is clear is that there are very serious repercussions associated with El Niño both on the composition and on dynamics of the coastal and marine ecosystems, and also the associated economic impacts are very evident. In light of the 2015-16 El Niño, some ecosystem and economic consequences of this phenomenon have been described in contrast systems (fisheries and ocean upwelling, coral reefs and mangroves), emphasizing the possible role of climate change and its consequences on marine biodiversity.Keywords: El Niño; Climate change; Coral reef; Mangrove; Upwelling; Fishery.. RESUMO / RESUMEN EFEITOS DO EL NIÑO EM ECOSSISTEMAS COSTEIROS E SERVIÇOS RELACIONADOSDesde 1980, os efeitos do fenômeno El Niño têm sido debatidos seriamente desde um ponto de vista ecológico e econômico. Após o desastre da pesca na década de 1980, em países como Peru e o Chile, e o fenômeno de branqueamento de corais detectados em todo o mundo devido às intensas mudanças nas condições oceanográficas, os efeitos deste fenômeno foram estudados de forma mais sistemática (desde El Niño, 1997 -98). Sem ter a certeza absoluta de que a mudança climática está aumentando a freqüência ou a intensidade de seus impactos, o que é claro é que há repercussões muito graves associadas a El Niño tanto na composição quanto na dinâmica dos ecossistemas costeiros e marinhos, e também os impactos econômicos associados são muito evidentes. À luz do El Niño 2015-16, algumas conseqüências ecossistêmicas e econômicas deste fenômeno foram descritas em sistemas contrastantes (pesca e zonas de ressurgência, recifes de corais e manguezais), enfatizando o possível papel das mudanças climáticas e suas conseqüências na biodiversidade marinha.Palavras-chave: El Niño; Mudança Climática; Recife de coral; Manguezal; Ressurgência; Pesca. EFECTOS DEL EL NIÑO EN ECOSISTEMAS COSTEROS Y SERVICIOS RELACIONADOSDesde los años '80 del siglo pasado, los efectos del fenómeno de El Niño se han empezado a contabilizar de forma muy rigurosa desde un punto de vista ecosistémico y económico. Tras la debacle pesquera que sufrida por países como Perú o Chile durante los años '80, o los fenómenos de blanqueo de coral detectados en diferentes partes del planeta debido a los intensos cambios de temperatura del agua y las condiciones oceanográficas, el efecto de este fenómeno se ha empezado a estudiar de forma más sistemática. Sin tener la certeza absoluta de si el cambio climático está incrementando frecuencia o intensidad de sus impactos, lo que está cla...

“…Floods and droughts commonly control the estuarine water flow, growth of mangrove forests, salinity, and transfer of material from the mainland to the sea. Recent reviews (MARENGO & ES-PINOZA 2016; in salinity, organic matter, contaminants, and nutrients induced by extreme floods and droughts have drastic effects on mangroves (PEREIRA et al 2013;COSTA et al 2016;SLOTERDIJK et al 2017).…”

“…In the Amazon coast, the ecology of estuaries with large mangrove forests was affected by the droughts caused by El Niño. During severe drought periods, higher than normal salinity occurred mainly during the dry season (COSTA et al 2016). Reduced rainfall decrease the fluvial contribution to the ocean and increase the salinity of estuaries located in the tropical coasts of Africa, Australia, and Brazil.…”
